"多层感官动静结合讲解法"在武术普修课中的实施——将被动的"鸭"变成主动的"人"

教学方法的改革是提高教学质量的重要途径。章以当前教学改革的新目标及现代教学理论的新要求为依据，结合武术自身特点的优势，在教学过程中，提出并实施“多层感官动静结合讲解法”。该法不仅能充分调动学生的积极性和主动性，激发学生的学习兴趣，把学生由过去在课堂上被动的被“填”的“鸭子”变成有思考能力的、有主观能动性的人，同时，极大地提高了学生的专业技能及逻辑思维能力。     

视频组播分层解决方案的研究

组播作为一种节约网络带宽、降低网络负载的有效手段,在视频传输中具有广阔的应用前景。本文针对组播中的会话内公平性问题,深入研究了多速率组播分层解决方案的实现机制,并基于目前的研究现状和进展指出了分层组播现存的有关问题。同时为分析分层解决方案在解决组播会话内公平性问题中的有效性,文中通过网络仿真器NS进行了实验评价。

Action groups as a participative strategy for leading whole-school health promotion: Results on implementation from the INCLUSIVE trial in English secondary schools

Education policy increasingly promotes action groups as a key strategy for student and/or staff participation in school improvement and whole-school health promotion. Such groups can coordinate multi-component interventions, increase participation and engagement, and enable local adaptations, but few process evaluations have assessed this. We evaluated fidelity, feasibility and acceptability of action groups as part of a trial of a whole-school intervention to reduce bullying and aggression and promote health in English secondary schools, which reported multiple health and educational impacts. Action groups involved students and staff, supported by external facilitators, and drew on data on student needs. They aimed to: coordinate implementation of restorative practices and a social and emotional competencies curriculum; review policies and rules; and enact local decisions to modify school environments. Our process evaluation used interviews, focus groups, observations and questionnaires to assess action groups’ fidelity, role in coordination, role in local adaptation, support from external facilitators and data on student needs, and acceptability in engaging members. Fidelity was high in the first two years but lower in the third year when external facilitators withdrew. Student needs data were perceived as useful, but views on external facilitators were mixed. Groups successfully reviewed policies and rules, planned activities and coordinated restorative practices, but were less successful in implementing the curriculum. Success was facilitated by the involvement of school leaders. Members reported high satisfaction and empowerment. Action groups are a promising strategy for leading whole-school health promotion. Implementation is supported by external facilitation, local data and involvement of senior managers.     

Violence in School: What Can We Do?

A common disruption to learning and stability in schools occurs when pupils fight or become aggressive. This paper considers the issues of anger management, violence control and fighting reduction through a counselling programme with a high-risk pupil in secondary school. It begins by examining some of the thinking on young people and violence and aggression. Then, the author considers the place of counselling in schools in relation to this issue. Interventions for the practitioner to consider are discussed, including how to make a clear diagnosis of the nature of violence for the particular youngster, an analysis of anger-triggers and an ambitious attempt to modify a belief-system that holds that 'might is right'. The author argues that occasional incidents of violent disruption are a reality in education, and while media reporting exaggerates the problem, schools need more imaginative strategies with the few targeted individuals than exclusion from school.     

基于语义主题树的搜索覆盖度层状拓展方法

为了提高用户对网站使用的效率,提高网站本体模型的搜索性能,研究一种高效的网页语义概念树构建方法,进行搜索覆盖度层状拓展。传统方法中,使用搜索引擎的词语相似度算法进行搜索拓展,利用规则、聚类等技术对形式背景进行约简,无法有效简历概念间的上下位关系,性能不好。提出一种基于语义主题树特征匹配的搜索覆盖度层状拓展方法,进行Web语义模型和主题树构建,构建特征空间互信息区域文档词频向量模型,对数据库中记录的属性字段进行归类抽象,形成概念汇聚点,实现语义主题树构建搜索覆盖度拓展设计,构建语义主题树特征匹配算法,优化搜索引擎对文本特征的搜索敏感度,提高搜索覆盖度,实现文本搜索覆盖度层状拓展。实验分析得出,该方法具有较好的文本特征分类结果,语义层次结构清晰,可以有效提高文本数据召回率和查准率,展示了较好的应用价值。

焙烧镁铝层状双氢氧化物对Cr（VI）的吸附

用液相非稳态共沉淀法制备了镁铝层双氢氧化物（Mg-Al LDHs）,Mg-Al LDHs于450℃焙烧转化为镁铝复合氧化物（LDO）。用TEM、FT-IR、XRD和粒度分布对Mg-AlLDHs和LDO进行表征分析,并研究了LDO对水体中C（rVI）的吸附行为。实验结果表明：LDO对C（rVI）有很强的吸附能力,其吸附动力学和吸附等温线分别符合准二级速率方程和Langmuir方程,吸附量随初始pH的增大、温度的升高和无机电解质浓度的增加而显著降低,探讨了吸附机理。
